  However, in the dehydrating device (solid-liquid separation device) of Patent Document 1, 17 filter bodies (laminated rotary filter bodies) are connected via a chain by two electric motors arranged in one direction in the axial direction of the rotation shaft. Therefore, the force for rotating the rotating shaft is biased in one axial direction in all the filter bodies. For this reason, the force with which the filter body conveys the solid component is biased in one direction in the axial direction, and there is a disadvantage that a large torsional force acts on the rotating shaft in the vicinity of the discharge port where the solid component becomes hard. As a result, the rotating shaft of the filter body may be damaged. In particular, when the length of the rotating shaft of the filter body is increased in order to increase the processing amount, the amount of twist due to a large torsional force acting on the rotating shaft increases, and therefore the rotating shaft is easily damaged. There is a point. As a countermeasure, it is conceivable to increase the strength of the rotating shaft by increasing the shaft diameter. However, in this case, in order to maintain the filtration capacity, it is necessary to increase the filter piece diameter by at least the shaft diameter of the rotating shaft. That is, since the diameter of the filter body (stacked rotary filter body) is also increased, there is a problem that the weight increases accordingly. Therefore, conventionally, there is a problem that it is difficult to suppress breakage of the rotating shaft while suppressing an increase in the weight of the rotating shaft and the laminated rotating filter body.

  The present invention has been made to solve the above-described problems, and one object of the present invention is to prevent damage to the rotating shaft while suppressing an increase in the weight of the rotating shaft and the laminated rotating filter body. An object of the present invention is to provide a solid-liquid separation device that can be suppressed.

And a second motor provided on the other side in the axial direction of the rotation shaft of the second laminated rotary filter disposed on the solid discharge port side. Accordingly, in the first laminated rotary filter body, the force for conveying the solid component is increased on one side in the axial direction, and in the second laminated rotary filter body, the force for conveying the solid component is on the other side in the axial direction. It becomes stronger on the direction side. As a result, since the force for conveying the solid component can be dispersed in a balanced manner on one side and the other side in the axial direction, the first laminated rotary filter body and the first layer on the solid discharge port side where the solid component becomes harder. 2 When the load (resistance) is increased by distributing the load (resistance) in a balanced manner on both ends of the shaft without the force of conveying the solid component of the laminated rotating filter being biased in one direction or the other in the axial direction Also, it is possible to suppress a large torsional force from acting on the rotating shaft. Thereby, it can suppress that the torsional force increases by the rotating shaft of a 1st laminated rotary filter body and a 2nd laminated rotary filter body resulting from the increase in load. As a result, it is possible to prevent damage to the rotating shaft without increasing the shaft diameter of the rotating shaft, and it is not necessary to increase the diameter of the laminated rotating filter body. While suppressing an increase in the weight of the rotating shaft, it is possible to suppress the breakage of the rotating shaft.

Thus, by increasing the axial length of the rotating shaft in order to increase the size of the solid-liquid separator, the solid component can be easily removed even when the amount of the solid component transported by each layered rotary filter increases. Can be transported. As a result, the solid-liquid separator can be easily increased in size, so that the throughput of the stock solution can be easily increased. In addition, since there is no need to increase the shaft diameter of the rotating shaft, even when creating a large solid-liquid separation device, simply increasing the number of filter pieces stacked using a common rotating shaft with the same shaft diameter. A shaped rotating filter body can be formed. As a result, the filter piece can be made common regardless of the size of the solid-liquid separator.

And a fourth motor. If comprised in this way, not only the 1st lamination | stacking rotary filter body by the side of a solid discharge port and a 2nd lamination | stacking rotary filter body but the 3rd lamination | stacking rotation filter body by the side of a stock solution supply port and a 4th lamination | stacking rotary filter The force for conveying the solid component of the body can be distributed in a balanced manner on the one direction side and the other direction side in the axial direction without being biased in one direction or the other direction in the axial direction.

In the solid-liquid separation device according to the first aspect, preferably, the motor is configured to rotationally drive the rotating shaft via a speed reducer. If comprised in this way, since the force of a motor can be amplified via a reduction gear and can be transmitted to a laminated rotary filter body, the drive force of a laminated rotary filter body can be enlarged easily.

If comprised in this way, it can suppress that a filtration groove is clogged by rocking | fluctuation of a large diameter disc filter piece and a small diameter disc filter piece. And by combining the configuration of such a filter piece and the configuration of the solid-liquid separation device according to one aspect described above, a large-diameter disc filter piece, a small-diameter disc filter piece, and a medium-diameter disc filter piece While suppressing clogging of the laminated rotary filter body formed by use, it is possible to suppress an increase in the weight of the rotary shaft and the laminated rotary filter body, and to prevent breakage of the rotary shaft.

In this case, preferably, the medium-diameter disc filter piece is made of resin. If comprised in this way, the weight of a laminated | stacked rotary filter body can be made light compared with the case where a medium diameter disc filter piece is formed with a metal. Thereby, even when it enlarges by increasing the number of lamination | stacking of a filter piece, it can suppress that the load concerning a rotating shaft becomes large.

The solid-liquid separation device according to the second aspect of the present invention includes a rotary shaft, a laminated rotary filter body including a plurality of filter pieces stacked along the rotary shaft, and a filtration groove formed between the filter pieces, And a plurality of laminated rotary filter bodies arranged in two upper and lower rows toward the solid discharge port so as to send the solid components of the supplied stock solution to the solid discharge port.

As a result, in each of the first laminated rotary filter body and the second laminated rotary filter body on the solid discharge port side, the force for conveying the solid component is distributed in a balanced manner on the one direction side and the other direction side in the axial direction. The solid component with the most load (resistance) applied to the rotating shaft is squeezed and conveyed from the solid discharge port, and is simultaneously driven synchronously from both ends of the rotating shaft of the first and second laminated rotary filter bodies. Since the first and second laminated rotary filter bodies are simultaneously driven and rotated in the same direction with the same driving force and rotational speed, the solid component is squeezed stably and uniformly without any torsional force acting on each rotating shaft. A solid component having a low water content can be discharged from the solid discharge port while being conveyed. In addition, since two motors are provided in each of the first laminated rotary filter body and the second laminated rotary filter body, the output of each motor can be reduced, so that the motor on the solid discharge port side Can be reduced in size. Conversely, when the output of each motor is not reduced, the driving force of the laminated rotary filter can be increased, so that the effect that the solid component can be strongly squeezed and conveyed can be added. .

The motor further includes a third motor provided on both the one side and the other side in the axial direction of the rotation axis of the third laminated rotary filter body, and an axial direction of the rotary shaft of the fourth laminated rotary filter body And a fourth motor provided on both the one side and the other side. As a result, in each of the third laminated rotary filter body and the fourth laminated rotary filter body on the stock solution supply port side, the force for conveying the solid component is distributed in a balanced manner on the one direction side and the other direction side in the axial direction. Since the third and fourth laminated rotary filter bodies are simultaneously driven and rotated in the same direction with the same driving force and rotational speed, a solid component can be stably and uniformly applied without a torsional force acting on each rotating shaft. Can be transported. In addition, since two motors are provided in each of the third laminated rotary filter body and the fourth laminated rotary filter body, the output of each motor can be reduced, so the motor on the stock solution supply port side Can be reduced in size. Conversely, when the output of each motor is not reduced, the driving force of the laminated rotary filter can be increased, so that an effect that the solid component can be strongly conveyed can be added.
